Description

Nucleoside analogs are a class of compounds that have been shown to exert antiviral and anticancer activity both in vitro and in vivo, and thus, have been the subject of widespread research for the treatment of viral infections. Nucleoside analogs are usually therapeutically inactive compounds that are converted by host or viral enzymes to their respective active anti-metabolites, which, in turn, may inhibit polymerases involved in viral or cell proliferation. The activation occurs by a variety of mechanisms, such as the addition of one or more phosphate groups and, or in combination with, other metabolic processes.

DETAILED DESCRIPTION

Definitions

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art. All patents, applications, published applications and other publications referenced herein are incorporated by reference in their entirety unless stated otherwise. In the event that there are a plurality of definitions for a term herein, those in this section prevail unless stated otherwise.

As used herein, any “R” group(s) such as, without limitation, R¹, R², R³, R⁴, R⁵, R⁶, R⁷, R⁸, R⁹, R¹⁰, R¹¹, R¹² and R¹³ represent substituents that can be attached to the indicated atom. An R group may be substituted or unsubstituted. If two “R” groups are described as being “taken together” the R groups and the atoms they are attached to can form a cycloalkyl, cycloalkenyl, aryl, heteroaryl or heterocycle. For example, without limitation, if R^(a) and R^(b) of an NR^(a) R^(b) group are indicated to be “taken together,” it means that they are covalently bonded to one another to form a ring:

In addition, if two “R” groups are described as being “taken together” with the atom(s) to which they are attached to form a ring as an alternative, the R groups are not limited to the variables or substituents defined previously.

Whenever a group is described as being “optionally substituted” that group may be unsubstituted or substituted with one or more of the indicated substituents. Likewise, when a group is described as being “unsubstituted or substituted” if substituted, the substituent(s) may be selected from one or more the indicated substituents. If no substituents are indicated, it is meant that the indicated “optionally substituted” or “substituted” group may be substituted with one or more group(s) individually and independently selected from alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aryl, heteroaryl, heterocyclyl, aryl(alkyl), heteroaryl(alkyl), (heterocyclyl)alkyl, hydroxy, alkoxy, acyl, cyano, halogen, thiocarbonyl, O-carbamyl, N-carbamyl, O-thiocarbamyl, N-thiocarbamyl, C-amido, N-amido, S-sulfonamido, N-sulfonamido, C-carboxy, O-carboxy, isocyanato, thiocyanato, isothiocyanato, nitro, silyl, sulfenyl, sulfinyl, sulfonyl, haloalkyl, haloalkoxy, trihalomethanesulfonyl, trihalomethanesulfonamido, an amino, a mono-substituted amino group and a di-substituted amino group.

As used herein, “C_(a) to C_(b)” in which “a” and “b” are integers refer to the number of carbon atoms in an alkyl, alkenyl or alkynyl group, or the number of carbon atoms in the ring of a cycloalkyl, cycloalkenyl, aryl, heteroaryl or heterocyclyl group. That is, the alkyl, alkenyl, alkynyl, ring of the cycloalkyl, ring of the cycloalkenyl, ring of the aryl, ring of the heteroaryl or ring of the heterocyclyl can contain from “a” to “b”, inclusive, carbon atoms. Thus, for example, a “C₁ to C₄ alkyl” group refers to all alkyl groups having from 1 to 4 carbons, that is, CH₃—, CH₃CH₂—, CH₃CH₂CH₂—, (CH₃)₂CH—, CH₃CH₂CH₂CH₂—, CH₃CH₂CH(CH₃)— and (CH₃)₃C—. If no “a” and “b” are designated with regard to an alkyl, alkenyl, alkynyl, cycloalkyl cycloalkenyl, aryl, heteroaryl or heterocyclyl group, the broadest range described in these definitions is to be assumed.

As used herein, “alkyl” refers to a straight or branched hydrocarbon chain that comprises a fully saturated (no double or triple bonds) hydrocarbon group. The alkyl group may have 1 to 20 carbon atoms (whenever it appears herein, a numerical range such as “1 to 20” refers to each integer in the given range; e.g., “1 to 20 carbon atoms” means that the alkyl group may consist of 1 carbon atom, 2 carbon atoms, 3 carbon atoms, etc., up to and including 20 carbon atoms, although the present definition also covers the occurrence of the term “alkyl” where no numerical range is designated). The alkyl group may also be a medium size alkyl having 1 to 10 carbon atoms. The alkyl group could also be a lower alkyl having 1 to 6 carbon atoms. The alkyl group of the compounds may be designated as “C₁-C₄ alkyl” or similar designations. By way of example only, “C₁-C₄ alkyl” indicates that there are one to four carbon atoms in the alkyl chain, i.e., the alkyl chain is selected from methyl, ethyl, propyl, iso-propyl, n-butyl, iso-butyl, sec-butyl and t-butyl. Typical alkyl groups include, but are in no way limited to, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tertiary butyl, pentyl and hexyl. The alkyl group may be substituted or unsubstituted.

As used herein, “alkenyl” refers to an alkyl group that contains in the straight or branched hydrocarbon chain one or more double bonds. An alkenyl group may be unsubstituted or substituted.

As used herein, “alkynyl” refers to an alkyl group that contains in the straight or branched hydrocarbon chain one or more triple bonds. An alkynyl group may be unsubstituted or substituted.

As used herein, “cycloalkyl” refers to a completely saturated (no double or triple bonds) mono- or multi-cyclic hydrocarbon ring system. When composed of two or more rings, the rings may be joined together in a fused fashion. Cycloalkyl groups can contain 3 to 10 atoms in the ring(s) or 3 to 8 atoms in the ring(s). A cycloalkyl group may be unsubstituted or substituted. Typical cycloalkyl groups include, but are in no way limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl and cyclooctyl.

As used herein, “cycloalkenyl” refers to a mono- or multi-cyclic hydrocarbon ring system that contains one or more double bonds in at least one ring; although, if there is more than one, the double bonds cannot form a fully delocalized pi-electron system throughout all the rings (otherwise the group would be “aryl,” as defined herein). When composed of two or more rings, the rings may be connected together in a fused fashion. A cycloalkenyl can contain 3 to 10 atoms in the ring(s) or 3 to 8 atoms in the ring(s). A cycloalkenyl group may be unsubstituted or substituted.

As used herein, “aryl” refers to a carbocyclic (all carbon) monocyclic or multicyclic aromatic ring system (including fused ring systems where two carbocyclic rings share a chemical bond) that has a fully delocalized pi-electron system throughout all the rings. The number of carbon atoms in an aryl group can vary. For example, the aryl group can be a C₆-C₁₄ aryl group, a C₆-C₁₀ aryl group, or a C₆ aryl group. Examples of aryl groups include, but are not limited to, benzene, naphthalene and azulene. An aryl group may be substituted or unsubstituted.

As used herein, “heteroaryl” refers to a monocyclic, bicyclic and tricyclic aromatic ring system (a ring system with fully delocalized pi-electron system) that contain(s) one or more heteroatoms (for example, 1 to 5 heteroatoms), that is, an element other than carbon, including but not limited to, nitrogen, oxygen and sulfur. The number of atoms in the ring(s) of a heteroaryl group can vary. For example, the heteroaryl group can contain 4 to 14 atoms in the ring(s), 5 to 10 atoms in the ring(s) or 5 to 6 atoms in the ring(s). Furthermore, the term “heteroaryl” includes fused ring systems where two rings, such as at least one aryl ring and at least one heteroaryl ring, or at least two heteroaryl rings, share at least one chemical bond. Examples of heteroaryl rings include, but are not limited to, furan, furazan, thiophene, benzothiophene, phthalazine, pyrrole, oxazole, benzoxazole, 1,2,3-oxadiazole, 1,2,4-oxadiazole, thiazole, 1,2,3-thiadiazole, 1,2,4-thiadiazole, benzothiazole, imidazole, benzimidazole, indole, indazole, pyrazole, benzopyrazole, isoxazole, benzoisoxazole, isothiazole, triazole, benzotriazole, thiadiazole, tetrazole, pyridine, pyridazine, pyrimidine, pyrazine, purine, pteridine, quinoline, isoquinoline, quinazoline, quinoxaline, cinnoline and triazine.

A heterocycle may optionally contain one or more unsaturated bonds situated in such a way, however, that a fully delocalized pi-electron system does not occur throughout all the rings. The heteroatom(s) is an element other than carbon including, but not limited to, oxygen, sulfur and nitrogen. A heterocycle may further contain one or more carbonyl or thiocarbonyl functionalities, so as to make the definition include oxo-systems and thio-systems such as lactams, lactones, cyclic imides, cyclic thioimides and cyclic carbamates. When composed of two or more rings, the rings may be joined together in a fused fashion. Additionally, any nitrogens in a heteroalicyclic may be quaternized. Heterocyclyl or heteroalicyclic groups may be unsubstituted or substituted.

or a pharmaceutically acceptable salt of the foregoing.

Additional examples of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, include the following:

or a pharmaceutically acceptable salt of the foregoing.

By neutralizing the charge on the phosphate moiety of Formula (I), or a pharmaceutically acceptable salt thereof, penetration of the cell membrane may be facilitated as a result of the increased lipophilicity of the compound. Once absorbed and taken inside the cell, the groups attached to the phosphorus can be easily removed by esterases, proteases and/or other enzymes. In some embodiments, the groups attached to the phosphorus can be removed by simple hydrolysis. Inside the cell, the phosphate thus released may then be metabolized by cellular enzymes to the diphosphate or the active triphosphate. Furthermore, in some embodiments, varying the substituents on a compound described herein, such as a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can help maintain the efficacy of the compound by reducing undesirable effects.

In some embodiments, varying the substituents on a compound described herein, such as a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can result in the 5′-O-phosphorous being a chiral center. In some embodiments, the 5′-O-phosphorous can be in the (R)-configuration. In some embodiments, the 5′-O-phosphorous can be in the (S)-configuration. Examples of the two configurations are:

In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be enriched in (R) or (S) configuration with respect to the 5′-O-phosphorous. For example, one of the (R) and (S) configuration with respect to the 5′-O-phosphorous atom can be present in an amount >50%, ≧75%, ≧90%, ≧95% or ≧99% compared to the amount of the other of the (R) or (S) configuration with respect to the 5′-O-phosphorous atom.

In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can act as a chain terminator of HCV replication. For example, compounds of Formula (I), or a pharmaceutically acceptable salt thereof, with a —C(R⁶)₃ moiety at the 2′-carbon position can be incorporated into an RNA chain of HCV and then no further elongation is observed to occur.

In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can have increased metabolic and/or plasma stability. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be more resistant to hydrolysis and/or more resistant to enzymatic transformations. For example, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can have increased metabolic stability, increased plasma stability, can be more resistant to hydrolysis and/or can be more resistant to enzymatic transformations compared to a compound that is identical in structure but for having two hydrogens in place of the two deuteriums at the 5′-position. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can have improved properties. A non-limiting list of example properties include, but are not limited to, increased biological half-life, increased bioavailability, increase potency, a sustained in vivo response, increased dosing intervals, decreased dosing amounts, decreased cytotoxicity, reduction in required amounts for treating disease conditions, reduction in viral load, reduction in time to seroconversion (i.e., the virus becomes undetectable in patient serum), increased sustained viral response, a reduction of morbidity or mortality in clinical outcomes, increased subject compliance, decreased liver conditions (such as liver fibrosis, liver cirrhosis and/or liver cancer), and compatibility with other medications. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can have a biological half-life of greater than 24 hours. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can have a biological half-life greater than a compound that is identical in structure but for having two hydrogens in place of the two deuteriums at the 5′-position. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can have more potent antiviral activity (for example, a lower EC₅₀ in an HCV replicon assay) as compared to the current standard of care. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, does not significantly inhibit mitochondrial function of the mitochondrial RNA polymerase. For example, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, is incorporated in the human mitochondrial RNA polymerase less than 10% compared to the natural 5′-triphosphate nucleotide with the same B¹.

Additionally, in some embodiments, the presence of a phosphoramidate or bis(POC) in a compound of Formula (I) or a pharmaceutically acceptable salt thereof, can increase the stability of the compound by inhibiting its degradation. Also, in some embodiments, the presence of a phosphoramidate or bis(POC) can make the compound more resistant to cleavage in vivo and provide sustained, extended efficacy. In some embodiments, a phosphoramidate or bis(POC) can facilitate the penetration of the cell membrane by a compound of Formula (I) or a pharmaceutically acceptable salt thereof, by making the compound more lipophilic. In some embodiments, a phosphoramidate or bis(POC) can have improved oral bioavailability, improved aqueous stability and/or reduced risk of byproduct-related toxicity. In some embodiments, for comparison purposes, a compound of Formula (I) or a pharmaceutically acceptable salt thereof, can be compared to a compound that is identical in structure but for having two hydrogens in place of the two deuteriums at the 5′-position.

Synthesis

Compounds of Formula (I) or a pharmaceutically acceptable salt thereof, and those described herein may be prepared in various ways. General synthetic routes to the compound of Formula (I), or a pharmaceutically acceptable salt thereof, and some examples of starting materials used to synthesize the compounds of Formula (I) or a pharmaceutically acceptable salt thereof, are shown in Schemes 1 and 2, and described herein. The routes shown and described herein are illustrative only and are not intended, nor are they to be construed, to limit the scope of the claims in any manner whatsoever. Those skilled in the art will be able to recognize modifications of the disclosed syntheses and to devise alternate routes based on the disclosures herein; all such modifications and alternate routes are within the scope of the claims.

Compounds of Formula (I) or a pharmaceutically acceptable salt thereof, can be prepared using various methods known to those skilled in the art. Examples of methods are shown in Schemes 1 and 2. Suitable phosphorus containing precursors can be commercially obtained or prepared by synthetic methods known to those skilled in the art. Examples of general structures of phosphorus containing precursors are shown in Schemes 1 and 2, and involve the use of phosphorochloridates. Suitable phosphorochloridates are commercially available and/or can be synthetically prepared.

One method for forming a compound of Formula (I) or a pharmaceutically acceptable salt thereof, is shown in Scheme 1. In Scheme 1, R^(1a), R^(2a), R^(3a), R^(4a), R^(5a), R^(6a), R^(7a) and B^(1a) can be the same as R¹, R², R³ R⁴, R⁵, R⁶, R⁷ and B¹ as described herein for Formula (I). In some embodiments, a compound of Formula (I) or a pharmaceutically acceptable salt thereof, can be generated from a compound of Formula (A) and a compound of Formula (B) using an organometallic reagent, such as a Grignard reagent. Suitable Grignard reagents are known to those skilled in the art and include, but are not limited to, alkylmagnesium chlorides and alkylmagnesium bromides. In other embodiments, an appropriate base can be used to form a compound of Formula (I). Examples of suitable bases include, but are not limited to, an amine base, such as an alkylamine (including mono-, di- and tri-alkylamines (e.g., triethylamine)), optionally substituted pyridines (e.g. collidine) and optionally substituted imidazoles (e.g., N-methylimidazole)).

A phosphorus containing precursor can be coupled to the nucleoside, for example, a compound of Formula (A). Following the coupling of the phosphorus containing precursor, any leaving groups can be cleaved under suitable conditions, such as hydrolysis. In Scheme 2, R^(1a), R^(2a), R^(3a), R^(4a), R^(5a), R^(6a), R^(7a), R^(8a), R^(9a), R^(10a) and B^(1a) can be the same as R¹, R², R³, R⁴, R⁵, R⁶, R⁷, R⁸, R⁹, R¹⁰ and B¹ as described herein for Formula (I). Further phosphorus containing groups can be added using methods known to those skilled in the art, for example using a pyrophosphate. If desired, one or more bases can be used during the addition of each phosphorus-containing group. Examples of suitable bases are described herein.

To reduce the formation of side products, one or more of the groups attached to the pentose ring can be protected with one or more suitable protecting groups. As an example, if R^(4a) and/or R^(5a) is/are hydroxy group(s), the hydroxy group(s) can be protected with suitable protecting groups, such as triarylmethyl and/or silyl groups. Examples of triarylmethyl groups include but are not limited to, trityl, monomethoxytrityl (MMTr), 4,4′-dimethoxytrityl (DMTr), 4,4′,4″-trimethoxytrityl (TMTr). 4,4′,4″-tris-(benzoyloxy) trityl (TBTr), 4,4′,4″-tris(4,5-dichlorophthalimido) trityl (CPTr), 4,4′,4″-tris(levulinyloxy) trityl (TLTr), p-anisyl-1-naphthylphenylmethyl, di-o-anisyl-1-naphthylmethyl, p-tolyldipheylmethyl, 3-(imidazolylmethyl)-4,4′-dimethoxytrityl, 9-phenylxanthen-9-yl (Pixyl), 9-(p-methoxyphenyl) xanthen-9-yl (Mox), 4-decyloxytrityl, 4-hexadecyloxytrityl, 4,4′-dioctadecyltrityl, 9-(4-octadecyloxyphenyl) xanthen-9-yl, 1,1′-bis-(4-methoxyphenyl)-1′-pyrenylmethyl, 4,4′,4″-tris-(tert-butylphenyl) methyl (TTTr) and 4,4′-di-3,5-hexadienoxytrityl. Examples of suitable silyl groups are described herein and include trimethylsilyl (TMS), tert-butyldimethylsilyl (TBDMS), triisopropylsilyl (TIPS), tert-butyldiphenylsilyl (TBDPS), tri-iso-propylsilyloxymethyl and [2-(trimethylsilyl)ethoxy]methyl. Alternatively, R^(4a) and/or R^(5a) can be protected by a single achiral or chiral protecting group, for example, by forming an orthoester, a cyclic acetal or a cyclic ketal. Suitable orthoesters include methoxymethylene acetal, ethoxymethylene acetal, 2-oxacyclopentylidene orthoester, dimethoxymethylene orthoester, 1-methoxyethylidene orthoester, 1-ethoxyethylidene orthoester, methylidene orthoester, phthalide orthoester 1,2-dimethoxyethylidene orthoester, and alpha-methoxybenzylidene orthoester; suitable cyclic acetals include methylene acetal, ethylidene acetal, t-butylmethylidene acetal, 3-(benzyloxy)propyl acetal, benzylidene acetal, 3,4-dimethoxybenzylidene acetal and p-acetoxybenzylidene acetal; and suitable cyclic ketals include 1-t-butylethylidene ketal, 1-phenylethylidene ketal, isopropylidene ketal, cyclopentylidene ketal, cyclohexylidene ketal, cycloheptylidene ketal and 1-(4-methoxyphenyl)ethylidene ketal.

Pharmaceutical Compositions

Some embodiments described herein relate to a pharmaceutical composition, that can include an effective amount of one or more compounds described herein (e.g., a compound of Formula (I), or a pharmaceutically acceptable salt thereof) and a pharmaceutically acceptable carrier, diluent, excipient or combination thereof. In some embodiments, the pharmaceutical composition can include a single diastereomer of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, (for example, a single diastereomer is present in the pharmaceutical composition at a concentration of greater than 99% compared to the total concentration of the other diastereomers). In other embodiments, the pharmaceutical composition can include a mixture of diastereomers of a compound of Formula (I), or a pharmaceutically acceptable salt thereof. For example, the pharmaceutical composition can include a concentration of one diastereomer of >50%, ≧60%, ≧70%, ≧80%, ≧90%, ≧95%, or ≧98%, as compared to the total concentration of the other diastereomers. In some embodiments, the pharmaceutical composition includes a 1:1 mixture of two diastereomers of a compound of Formula (I), or a pharmaceutically acceptable salt thereof.

The term “pharmaceutical composition” refers to a mixture of one or more compounds disclosed herein with other chemical components, such as diluents or carriers. The pharmaceutical composition facilitates administration of the compound to an organism. Pharmaceutical compositions can also be obtained by reacting compounds with inorganic or organic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid and salicylic acid. Pharmaceutical compositions will generally be tailored to the specific intended route of administration. A pharmaceutical composition is suitable for human and/or veterinary applications.

The term “physiologically acceptable” defines a carrier, diluent or excipient that does not abrogate the biological activity and properties of the compound.

As used herein, a “carrier” refers to a compound that facilitates the incorporation of a compound into cells or tissues. For example, without limitation, dimethyl sulfoxide (DMSO) is a commonly utilized carrier that facilitates the uptake of many organic compounds into cells or tissues of a subject.

As used herein, a “diluent” refers to an ingredient in a pharmaceutical composition that lacks pharmacological activity but may be pharmaceutically necessary or desirable. For example, a diluent may be used to increase the bulk of a potent drug whose mass is too small for manufacture and/or administration. It may also be a liquid for the dissolution of a drug to be administered by injection, ingestion or inhalation. A common form of diluent in the art is a buffered aqueous solution such as, without limitation, phosphate buffered saline that mimics the composition of human blood.

As used herein, an “excipient” refers to an inert substance that is added to a pharmaceutical composition to provide, without limitation, bulk, consistency, stability, binding ability, lubrication, disintegrating ability etc., to the composition. A “diluent” is a type of excipient.

The pharmaceutical compositions described herein can be administered to a human patient per se, or in pharmaceutical compositions where they are mixed with other active ingredients, as in combination therapy, or carriers, diluents, excipients or combinations thereof. Proper formulation is dependent upon the route of administration chosen. Techniques for formulation and administration of the compounds described herein are known to those skilled in the art.

The pharmaceutical compositions disclosed herein may be manufactured in a manner that is itself known, e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or tableting processes. Additionally, the active ingredients are contained in an amount effective to achieve its intended purpose. Many of the compounds used in the pharmaceutical combinations disclosed herein may be provided as salts with pharmaceutically compatible counterions.

Multiple techniques of administering a compound exist in the art including, but not limited to, oral, rectal, topical, aerosol, injection and parenteral delivery, including intramuscular, subcutaneous, intravenous, intramedullary injections, intrathecal, direct intraventricular, intraperitoneal, intranasal and intraocular injections.

One may also administer the compound in a local rather than systemic manner, for example, via injection of the compound directly into the infected area, often in a depot or sustained release formulation. Furthermore, one may administer the compound in a targeted drug delivery system, for example, in a liposome coated with a tissue-specific antibody. The liposomes will be targeted to and taken up selectively by the organ.

The compositions may, if desired, be presented in a pack or dispenser device which may contain one or more unit dosage forms containing the active ingredient. The pack may for example comprise metal or plastic foil, such as a blister pack. The pack or dispenser device may be accompanied by instructions for administration. The pack or dispenser may also be accompanied with a notice associated with the container in form prescribed by a governmental agency regulating the manufacture, use, or sale of pharmaceuticals, which notice is reflective of approval by the agency of the form of the drug for human or veterinary administration. Such notice, for example, may be the labeling approved by the U.S. Food and Drug Administration for prescription drugs, or the approved product insert. Compositions that can include a compound described herein formulated in a compatible pharmaceutical carrier may also be prepared, placed in an appropriate container, and labeled for treatment of an indicated condition.

There are a variety of genotypes of HCV, and a variety of subtypes within each genotype. For example, at present it is known that there are eleven (numbered 1 through 11) main genotypes of HCV, although others have classified the genotypes as 6 main genotypes. Each of these genotypes is further subdivided into subtypes (1a-1c; 2a-2c; 3a-3b; 4a-4e; 5a; 6a; 7a-7b; 8a-8b; 9a; 10a; and 11a). In some embodiments, an effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, or a pharmaceutical composition that includes an effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be effective to treat at least one genotype of HCV. In some embodiments, a compound described herein (for example, a compound of Formula (I), or a pharmaceutically acceptable salt thereof) can be effective to treat all 11 genotypes of HCV. In some embodiments, a compound described herein (for example, a compound of Formula (I), or a pharmaceutically acceptable salt thereof) can be effective to treat 3 or more, 5 or more, 7 or more, or 9 or more genotypes of HCV. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof can be more effective against a larger number of HCV genotypes than the standard of care. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be more effective against a particular HCV genotype than the standard of care (such as genotype 1, 2, 3, 4, 5 and/or 6).

Various indicators for determining the effectiveness of a method for treating a HCV infection are known to those skilled in the art. Examples of suitable indicators include, but are not limited to, a reduction in viral load, a reduction in viral replication, a reduction in time to seroconversion (virus undetectable in patient serum), an increase in the rate of sustained viral response to therapy, a reduction of morbidity or mortality in clinical outcomes, a reduction in the rate of liver function decrease; stasis in liver function; improvement in liver function; reduction in one or more markers of liver dysfunction, including alanine transaminase, aspartate transaminase, total bilirubin, conjugated bilirubin, gamma glutamyl transpeptidase and/or other indicator of disease response. Similarly, successful therapy with an effective amount of a compound or a pharmaceutical composition described herein (for example, a compound of Formula (I), or a pharmaceutically acceptable salt thereof) can reduce the incidence of liver cancer in HCV infected subjects.

In some embodiments, an effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, is an amount that is effective to reduce HCV viral titers to undetectable levels, for example, to about 100 to about 500, to about 50 to about 100, to about 10 to about 50, or to about 15 to about 25 international units/mL serum. In some embodiments, an effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, is an amount that is effective to reduce HCV viral load compared to the HCV viral load before administration of the compound of Formula (I), or a pharmaceutically acceptable salt thereof. For example, wherein the HCV viral load is measured before administration of the compound of Formula (I), or a pharmaceutically acceptable salt thereof, and again after completion of the treatment regime with the compound of Formula (I), or a pharmaceutically acceptable salt thereof (for example, 1 month after completion). In some embodiments, an effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be an amount that is effective to reduce HCV viral load to lower than about 25 international units/mL serum. In some embodiments, an effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, is an amount that is effective to achieve a reduction in HCV viral titer in the serum of the subject in the range of about 1.5-log to about a 2.5-log reduction, about a 3-log to about a 4-log reduction, or a greater than about 5-log reduction compared to the viral load before administration of the compound of Formula (I), or a pharmaceutically acceptable salt thereof. For example, the HCV viral load can be measured before administration of the compound of Formula (I), or a pharmaceutically acceptable salt thereof, and again after completion of the treatment regime with the compound of Formula (I), or a pharmaceutically acceptable salt thereof (for example, 1 month after completion).

In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can result in at least a 1, 2, 3, 4, 5, 10, 15, 20, 25, 50, 75, 100-fold or more reduction in the replication of the hepatitis C virus relative to pre-treatment levels in a subject, as determined after completion of the treatment regime (for example, 1 month after completion). In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can result in a reduction of the replication of the hepatitis C virus relative to pre-treatment levels in the range of about 2 to about 5 fold, about 10 to about 20 fold, about 15 to about 40 fold, or about 50 to about 100 fold. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can result in a reduction of the hepatitis C virus replication in the range of 1 to 1.5 log, 1.5 log to 2 log, 2 log to 2.5 log, 2.5 to 3 log, 3 log to 3.5 log or 3.5 to 4 log more reduction of the hepatitis C virus replication compared to the reduction of the hepatitis C virus reduction achieved by pegylated interferon in combination with ribavirin, administered according to the standard of care, or may achieve the same reduction as that standard of care therapy in a shorter period of time, for example, in one month, two months, or three months, as compared to the reduction achieved after six months of standard of care therapy with ribavirin and pegylated interferon.

In some embodiments, an effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, is an amount that is effective to achieve a sustained viral response, for example, non-detectable or substantially non-detectable HCV RNA (e.g., less than about 500, less than about 200, less than about 100, less than about 25, or less than about 15 international units per milliliter serum) is found in the subject's serum for a period of at least about one month, at least about two months, at least about three months, at least about four months, at least about five months, or at least about six months following cessation of therapy.

In some embodiments, an effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can reduce a level of a marker of liver fibrosis by at least about 10%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45%, at least about 50%, at least about 55%, at least about 60%, at least about 65%, at least about 70%, at least about 75%, or at least about 80%, or more, compared to the level of the marker in an untreated subject, or to a placebo-treated subject. Methods of measuring serum markers are known to those skilled in the art and include immunological-based methods, e.g., enzyme-linked immunosorbent assays (ELISA), radioimmunoassays, and the like, using antibody specific for a given serum marker. A non-limiting list of examples of markers includes measuring the levels of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transpeptidase (GGT) and total bilirubin (TBIL) using known methods. In general, an ALT level of less than about 45 IU/L (international units/liter), an AST in the range of 10-34 IU/L, ALP in the range of 44-147 IU/L, GGT in the range of 0-51 IU/L, TBIL in the range of 0.3-1.9 mg/dL is considered normal. In some embodiments, an effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be an amount effective to reduce ALT, AST, ALP, GGT and/or TBIL levels to with what is considered a normal level.

Subjects who are clinically diagnosed with HCV infection include “naïve” subjects (e.g., subjects not previously treated for HCV, particularly those who have not previously received IFN-alpha-based and/or ribavirin-based therapy) and individuals who have failed prior treatment for HCV (“treatment failure” subjects). Treatment failure subjects include “non-responders” (i.e., subjects in whom the HCV titer was not significantly or sufficiently reduced by a previous treatment for HCV (≦0.5 log IU/mL), for example, a previous IFN-alpha monotherapy, a previous IFN-alpha and ribavirin combination therapy, or a previous pegylated IFN-alpha and ribavirin combination therapy); and “relapsers” (i.e., subjects who were previously treated for HCV, for example, who received a previous IFN-alpha monotherapy, a previous IFN-alpha and ribavirin combination therapy, or a previous pegylated IFN-alpha and ribavirin combination therapy, whose HCV titer decreased, and subsequently increased).

In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered to a treatment failure subject suffering from HCV. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered to a non-responder subject suffering from HCV. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered to a relapsed subject suffering from HCV.

After a period of time, infectious agents can develop resistance to one or more therapeutic agents. The term “resistance” as used herein refers to a viral strain displaying a delayed, lessened and/or null response to a therapeutic agent(s). For example, after treatment with an antiviral agent, the viral load of a subject infected with a resistant virus may be reduced to a lesser degree compared to the amount in viral load reduction exhibited by a subject infected with a non-resistant strain. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered to a subject infected with an HCV strain that is resistant to one or more different anti-HCV agents (for example, an agent used in a conventional standard of care). In some embodiments, development of resistant HCV strains is delayed when a subject is treated with a compound of Formula (I), or a pharmaceutically acceptable salt thereof, compared to the development of HCV strains resistant to other HCV drugs (such as an agent used in a conventional standard of care).

In some embodiments, an effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered to a subject for whom other anti-HCV medications are contraindicated. For example, administration of pegylated interferon alpha in combination with ribavirin is contraindicated in subjects with hemoglobinopathies (e.g., thalassemia major, sickle-cell anemia) and other subjects at risk from the hematologic side effects of current therapy. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be provided to a subject that is hypersensitive to interferon and/or ribavirin.

Some subjects being treated for HCV experience a viral load rebound. The term “viral load rebound” as used herein refers to a sustained ≧0.5 log IU/mL increase of viral load above nadir before the end of treatment, where nadir is a ≧0.5 log IU/mL decrease from baseline. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered to a subject experiencing viral load rebound, or can prevent such viral load rebound when used to treat the subject.

The standard of care for treating HCV has been associated with several side effects (adverse events). In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can decrease the number and/or severity of side effects that can be observed in HCV patients being treated with ribavirin and pegylated interferon according to the standard of care. Examples of side effects include, but are not limited to fever, malaise, tachycardia, chills, headache, arthralgias, myalgias, fatigue, apathy, loss of appetite, nausea, vomiting, cognitive changes, asthenia, drowsiness, lack of initiative, irritability, confusion, depression, severe depression, suicidal ideation, anemia, low white blood cell counts, and thinning of hair. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be provided to a subject that discontinued a HCV therapy because of one or more adverse effects or side effects associated with one or more other HCV agents (for example, an agent used in a conventional standard of care).

Table 4 provides some embodiments of the percentage improvement obtained using a compound of Formula (I), or a pharmaceutically acceptable salt thereof, as compared to the standard of care. Examples include the following: in some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, results in a percentage of non-responders that is 10% less than the percentage of non-responders receiving the standard of care. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, results in a number of side effects that is in the range of about 10% to about 30% less than compared to the number of side effects experienced by a subject receiving the standard of care; and in some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, results in a severity of a side effect (such as one of those described herein) that is 25% less than compared to the severity of the same side effect experienced by a subject receiving the standard of care. Methods of quantifying the severity of a side effect are known to those skilled in the art.

As used herein, a “subject” refers to an animal that is the object of treatment, observation or experiment. “Animal” includes cold- and warm-blooded vertebrates and invertebrates such as fish, shellfish, reptiles and, in particular, mammals. “Mammal” includes, without limitation, mice, rats, rabbits, guinea pigs, dogs, cats, sheep, goats, cows, horses, primates, such as monkeys, chimpanzees, and apes, and, in particular, humans. In some embodiments, the subject is human.

As used herein, the terms “treating,” “treatment,” “therapeutic,” or “therapy” do not necessarily mean total cure or abolition of the disease or condition. Any alleviation of any undesired signs or symptoms of a disease or condition, to any extent can be considered treatment and/or therapy. Furthermore, treatment may include acts that may worsen the patient's overall feeling of well-being or appearance.

The terms “therapeutically effective amount” and “effective amount” are used to indicate an amount of an active compound, or pharmaceutical agent, that elicits the biological or medicinal response indicated. For example, an effective amount of compound can be the amount needed to prevent, alleviate or ameliorate symptoms of disease or prolong the survival of the subject being treated This response may occur in a tissue, system, animal or human and includes alleviation of the signs or symptoms of the disease being treated. Determination of an effective amount is well within the capability of those skilled in the art, in view of the disclosure provided herein. The effective amount of the compounds disclosed herein required as a dose will depend on the route of administration, the type of animal, including human, being treated, and the physical characteristics of the specific animal under consideration. The dose can be tailored to achieve a desired effect, but will depend on such factors as weight, diet, concurrent medication and other factors which those skilled in the medical arts will recognize.

As will be readily apparent to one skilled in the art, the useful in vivo dosage to be administered and the particular mode of administration will vary depending upon the age, weight, the severity of the affliction, and mammalian species treated, the particular compounds employed, and the specific use for which these compounds are employed. The determination of effective dosage levels, that is the dosage levels necessary to achieve the desired result, can be accomplished by one skilled in the art using routine methods, for example, human clinical trials and in vitro studies.

The dosage may range broadly, depending upon the desired effects and the therapeutic indication. Alternatively dosages may be based and calculated upon the surface area of the patient, as understood by those of skill in the art. Although the exact dosage will be determined on a drug-by-drug basis, in most cases, some generalizations regarding the dosage can be made. The daily dosage regimen for an adult human patient may be, for example, an oral dose of between 0.01 mg and 3000 mg of each active ingredient, preferably between 1 mg and 700 mg, e.g. 5 to 200 mg. The dosage may be a single one or a series of two or more given in the course of one or more days, as is needed by the subject. In some embodiments, the compounds will be administered for a period of continuous therapy, for example for a week or more, or for months or years. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered less frequently compared to the frequency of administration of an agent within the standard of care. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered one time per day. For example, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered one time per day to a subject suffering from a HCV infection. In some embodiments, the total time of the treatment regime with a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be less compared to the total time of the treatment regime with the standard of care.

In instances where human dosages for compounds have been established for at least some condition, those same dosages may be used, or dosages that are between about 0.1% and 500%, more preferably between about 25% and 250% of the established human dosage. Where no human dosage is established, as will be the case for newly-discovered pharmaceutical compositions, a suitable human dosage can be inferred from ED₅₀ or ID₅₀ values, or other appropriate values derived from in vitro or in vivo studies, as qualified by toxicity studies and efficacy studies in animals.

In cases of administration of a pharmaceutically acceptable salt, dosages may be calculated as the free base. As will be understood by those of skill in the art, in certain situations it may be necessary to administer the compounds disclosed herein in amounts that exceed, or even far exceed, the above-stated, preferred dosage range in order to effectively and aggressively treat particularly aggressive diseases or infections.

Dosage amount and interval may be adjusted individually to provide plasma levels of the active moiety which are sufficient to maintain the modulating effects, or minimal effective concentration (MEC). The MEC will vary for each compound but can be estimated from in vitro data. Dosages necessary to achieve the MEC will depend on individual characteristics and route of administration. However, HPLC assays or bioassays can be used to determine plasma concentrations. Dosage intervals can also be determined using MEC value. Compositions should be administered using a regimen which maintains plasma levels above the MEC for 10-90% of the time, preferably between 30-90% and most preferably between 50-90%. In cases of local administration or selective uptake, the effective local concentration of the drug may not be related to plasma concentration.

It should be noted that the attending physician would know how to and when to terminate, interrupt, or adjust administration due to toxicity or organ dysfunctions. Conversely, the attending physician would also know to adjust treatment to higher levels if the clinical response were not adequate (precluding toxicity). The magnitude of an administrated dose in the management of the disorder of interest will vary with the severity of the condition to be treated and to the route of administration. The severity of the condition may, for example, be evaluated, in part, by standard prognostic evaluation methods. Further, the dose and perhaps dose frequency, will also vary according to the age, body weight, and response of the individual patient. A program comparable to that discussed above may be used in veterinary medicine.

Compounds disclosed herein can be evaluated for efficacy and toxicity using known methods. For example, the toxicology of a particular compound, or of a subset of the compounds, sharing certain chemical moieties, may be established by determining in vitro toxicity towards a cell line, such as a mammalian, and preferably human, cell line. The results of such studies are often predictive of toxicity in animals, such as mammals, or more specifically, humans. Alternatively, the toxicity of particular compounds in an animal model, such as mice, rats, rabbits, or monkeys, may be determined using known methods. The efficacy of a particular compound may be established using several recognized methods, such as in vitro methods, animal models, or human clinical trials. When selecting a model to determine efficacy, the skilled artisan can be guided by the state of the art to choose an appropriate model, dose, route of administration and/or regime.

In still other embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered concomitantly with one or more additional agent(s). In yet still other embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered subsequent to the administration of at least one additional agent. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered subsequent to the administration of all additional agents.

In some embodiments, the combination of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, in combination with one or more additional agent(s) in FIGS. 1-9 (including pharmaceutically acceptable salts and prodrugs thereof) can result in an additive effect. In some embodiments, the combination of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, in combination with one or more additional agent(s) in FIGS. 1-9 (including pharmaceutically acceptable salts and prodrugs thereof) can result in a synergistic effect. In some embodiments, the combination of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, in combination with one or more additional agent(s) in FIGS. 1-9 (including pharmaceutically acceptable salts and prodrugs thereof) can result in a strongly synergistic effect. In some embodiments, the combination of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, in combination with one or more additional agent(s) in FIGS. 1-9 (including pharmaceutically acceptable salts and prodrugs thereof) is not antagonistic.

As used herein, the term “antagonistic” means that the activity of the combination of compounds is less compared to the sum of the activities of the compounds in combination when the activity of each compound is determined individually (i.e. as a single compound). As used herein, the term “synergistic effect” means that the activity of the combination of compounds is greater than the sum of the individual activities of the compounds in the combination when the activity of each compound is determined individually. As used herein, the term “additive effect” means that the activity of the combination of compounds is about equal to the sum of the individual activities of the compound in the combination when the activity of each compound is determined individually.

A potential advantage of utilizing a compound of Formula (I), or a pharmaceutically acceptable salt thereof, in combination with one or more additional agent(s) in FIGS. 1-9 (including pharmaceutically acceptable salts thereof) may be a reduction in the required amount(s) of one or more compounds of FIGS. 1-9 (including pharmaceutically acceptable salts thereof) that is effective in treating a disease condition disclosed herein (for example, HCV), as compared to the amount required to achieve same therapeutic result when one or more compounds of FIGS. 1-9 (including pharmaceutically acceptable salts thereof) are administered without a compound of Formula (I), or a pharmaceutically acceptable salt thereof. For example, the amount of a compound in FIGS. 1-9 (including a pharmaceutically acceptable salt thereof), can be less compared to the amount of the compound in FIGS. 1-9 (including a pharmaceutically acceptable salt thereof), needed to achieve the same viral load reduction when administered as a monotherapy.

Example 1 Compound 1

Compound 1 was prepared according to the scheme provide above. 3-Neck 3 L flask was charged with 2′-methyluridine (129 g, 500 mmol, 1.0 eq.), triphenylphosphine (196.5 g, 750 mmol, 1.5 eq.), imidazole (51 g, 750 mmol, 1.5 eq.) and anhydrous THF (750 mL). With stirring under an argon atmosphere, iodine (143.4 g, 565 mmol, 1.13 eq.) was added as a solution in THF (˜300 mL), while maintaining the temperature below 25° C. The mixture was stirred overnight at room temperature (RT). THF was replaced by MeOH under reduced pressure. Compound 1-1 precipitated from methanol. The solid was aged overnight at 0° C., filtered off, washed with cold MeOH and dried under reduced pressure at 45-50° C. to yield 1-1 (114.6 g, 62%).

To a suspension of 1-1 (114.2 g, 310 mmol, 1 eq.) in MeOH (350 mL) was added sodium methoxide (176 mL 25% in MeOH, 775 mmol, 2.5 eq.). The mixture was heated at 60° C. for 3 h. HPLC showed complete conversion of 1-1 to 1-2. The mixture was cooled down to RT, and the excess of sodium methoxide was neutralized to pH ˜5-7 with acetic acid (˜30 mL) while maintaining the temperature below 25° C. Compound 1-2 precipitated during the addition of acetic acid. The solid was aged overnight at 0° C., isolated by filtration, washed with cold MeOH and dried under reduced pressure at 45° C. to yield 1-2 (60.9 g, 80.8%).

To a stirred at 0° C. slurry of 1-2 (28.8 g, 120 mmol, 1.0 eq.) in CH₃CN (240 mL) was added Et₃N.3HF (9.77 mL, 60 mmol, 0.5 eq., 1.5 eq. of HF) followed by addition of N-iodosuccinimide (35.1 g, 156 mmol, 1.3 eq.). Cooling was removed, and the mixture was stirred at RT for 2 h. Compound 1-3 precipitated. Compound 1-3 was filtered off, washed with DCM until the filtrate became colorless (3×) and dried under vacuum to give 1-3 (27.7 g, 59.8%) as a slightly yellow powder. The mother liquor (83% HPLC, 13% (β-isomer) was concentrated under reduced pressure to an oil. The oil was diluted with DCM (˜100 mL). The solution was added to a stirred 10% aqueous solution of potassium bicarbonate (150 mL), followed by addition of sodium thiosulfate (˜5 g as pentahydrate). A precipitate formed. The precipitate was isolated by filtration, washed with water followed by cold IPA and dried under reduced pressure to yield a second crop of compound C (8.0 g, 17%). The overall yield of 1-3 was (35.7 g, 76.8%).

Route 1: A solution of 1-3 (30.88 g, 80 mmol, 1.0 eq.) and imidazole (19.0 g, 280 mmol, 3.5 eq.) in DMF (140 mL) was treated with chlorotriethylsilane (33.5 mL, 200 mmol, 2.5 eq.) while maintaining the temperature below 25° C.

With stirring, TFA (18.4 mL, 240 mmol, 3 eq.) was added slowly to pH 3.5 while maintaining the temperature below 20-25° C. Crude 1-4 was added to the flask as a solution in DCM (250 mL). The mixture was stirred vigorously. mCPBA (99 g as 70%, 400 mmol, 5 eq.) was added portion-wise over ˜15 mins. The reaction temperature was maintained below 25° C. The mixture gradually became acidic (pH <1.5 in˜1 h), and the pH was maintained between 1.8-2 by dropwise addition of 2N aqueous NaOH. After 6 h, the pH was brought to 3.5, and the mixture was stirred overnight (overall: 40 mL, 80 mmol, 1 eq. of NaOH).

The reaction was quenched by the addition of sodium thiosulphate (119 g as pentahydrate, 480 mmol, 1.2 eq. to mCPBA) while maintaining the temperature below 25° C. The mixture was subjected to reduced pressure to remove DCM. MTBE (˜200 mL) was added. The mixture was stirred for ˜10 mins. The mixture was then filtered, and the organic layer was separated. The aqueous phase was washed with MTBE (3×50 mL). The combined MTBE extracts were washed with 10% aqueous potassium bicarbonate (150 mL) followed by water. The organic solution was filtered through a silica gel plug (60 g, 15×95 mm), and additional MTBE (˜150 mL) was used to elute the compound. The combined organic solution was concentrated to a thick slurry (˜77 g, ˜40 mL MTBE) which was diluted with hexane (325 mL). The resulted slurry was stirred for 15 mins at reflux, cooled to RT and left at 0° C. overnight. Compound 1-5 (24.4 g, 60.5%) was isolated by filtration, washed with cold hexane and dried under reduced pressure. The mother liquor (˜20 g) was separated by column chromatography (350 g, step-wise gradient from 30 to 50% ethyl acetate-hexane). The desired fractions were concentrated, and 1-5 was isolated by crystallization from hexane (50 mL) to yield a second crop of 1-5 (3.3 g (8.2%).

Route 2: Compound 1-3 (9.65 g, 25 mmol, 1.0 eq.) was silylated as described for Route 1 to furnish the crude bis-triethylsilyl ether (20 g).

The crude bis-triethylsilyl ether was added to the flask as a solution in DCM (60 mL). With stirring, mCPBA (27.7 g as 70%, 112.5 mmol, 4.5 eq.) was added portionwise over ˜5 mins. The reaction was stirred while maintaining the temperature below 25° C. The pH gradually decreased, and di-potassium hydrogenphosphate (4 g, 24 mmol, ˜1 eq) was used to maintain the pH at approx. 3.5-4.5. The mixture was stirred overnight.

Sodium sulfite (17 g, 135 mmol, 1.2 eq. to mCPBA) was added while maintaining the temperature below 25° C. A solution of potassium carbonate (10 g) in water (˜30 mL) was added to pH-8. A precipitate was filtered off and washed with DCM (˜50 mL). The biphasic filtrate was transferred to a separating funnel. The organic layer was separated, the aqueous layer was washed with DCM (3×15 mL). The combined organic solution was concentrated to a semi-crystalline residue, which was partitioned between IPAC (60 mL) and 10% potassium bicarbonate (50 mL). The organic layer was separated, washed with water and concentrated under reduced pressure to give a crystalline residue (18 g).

The crude compound was dissolved in n-butylamine (20 mL) using rotovap agitation under cooling. The solution was concentrated under vacuum, and the residue was dissolved in MTBE (˜50 mL). 2N Aqueous HCl was added to pH ˜2 (˜40 mL). The organic layer was separated, and washed sequentially with water, half-saturated sodium bicarbonate and water. MTBE was replaced with ACN under reduced pressure. The volume of the solution was adjusted to ˜60 mL with ACN. The solution was seeded with 1-5 crystals. The precipitated 1-5 was aged overnight at 0° C., isolated by filtration, washed with a small amount of cold ACN and dried under vacuum to give compound D (7.09 g, 55%). The mother liquor was separated by column chromatography (100 g, step-wise gradient from 25 to 50% ethyl acetate-hexane). The desired fractions were concentrated, and 1-5 was isolated by crystallization from hexane (˜30 mL) to yield a second crop of 1-5 (2.6 g, 20.6%).

Dry nucleoside (0.05 mmol) is dissolved in the mixture of PO(OMe)₃ (0.7 mL) and pyridine (0.3 mL). The mixture is evaporated in vacuum for 15 mins at bath temperature (42° C.), than cooled down to RT. N-Methylimidazole (0.009 mL, 0.11 mmol) is added followed by POCl₃ (9 μL, 0.11 mmol), and the mixture is kept at RT for 20-40 mins. The reaction is controlled by LCMS and monitored by the appearance of corresponding nucleoside 5′-monophosphate. After completion, tetrabutylammonium salt of pyrophosphate (150 mg) is added, followed by DMF (0.5 mL) to get a homogeneous solution. After 1.5 h at ambient temperature, the reaction is diluted with water (10 mL) and loaded on the column HiLoad 16/10 with Q Sepharose High Performance. Separation is done in a linear gradient of NaCl from 0 to 1N in 50 mM TRIS-buffer (pH 7.5). Triphosphate is eluted at 75-80% B. Corresponding fractions are concentrated.

Example A HCV Replicon Assay

Cells

Huh-7 cells containing the self-replicating, subgenomic HCV replicon with a stable luciferase (LUC) reporter were cultured in Dulbecco's modified Eagle's medium (DMEM) containing 2 mM L-glutamine and supplemented with 10% heat-inactivated fetal bovine serum (FBS), 1% penicillin-streptomyocin, 1% nonessential amino acids, and 0.5 mg/mL G418.

Determination of Anti-HCV Activity

Determination of 50% inhibitory concentration (EC₅₀) of compounds in HCV replicon cells were performed by the following procedure. On the first day, 5,000 HCV replicon cells were plated per well in a 96-well plate. On the following day, test compounds were solubilized in 100% DMSO to 100× the desired final testing concentration. Each compound was then serially diluted (1:3) up to 9 different concentrations. Compounds in 100% DMSO were reduced to 10% DMSO by diluting 1:10 in cell culture media. The compounds were diluted to 10% DMSO with cell culture media, which were used to dose the HCV replicon cells in 96-well format. The final DMSO concentration was 1%. The HCV replicon cells were incubated at 37° C. for 72 h. At 72 h, cells were processed when the cells were still subconfluent. Compounds that reduced the LUC signal were determined by Bright-Glo Luciferase Assay (Promega, Madison, Wis.). % Inhibition was determined for each compound concentration in relation to the control cells (untreated HCV replicon) to calculate the EC₅₀. Compounds 1 and 2 both had an EC₅₀ of less than <1 μM.

Example B NS5B Inhibition Assay

The enzyme activity of NS5B570-Con1 (Delta-21) is measured as an incorporation of tritiated NMP into acid-insoluble RNA products. The complementary IRES (cIRES) RNA sequence is used as a template, corresponding to 377 nucleotides from the 3′-end of HCV (−) strand RNA of the Con-1 strain, with a base content of 21% Ade, 23% Ura, 28% Cyt, and 28% Gua. The cIRES RNA is transcribed in vitro using a T7 transcription kit (Ambion, Inc.) and purified using the Qiagen RNeasy maxi kit. HCV polymerase reactions contain 50 nM NS5B570-Con1, 50 nM cIRES RNA, about 0.5 μCi tritiated NTP, 1 μm of competing cold NTP, 20 mM NaCl, 40 mM Tris-HCl (pH 8.0), 4 mM dithiothreitol, and 4 mM MgCl₂. Standard reactions are incubated for 2 h at 37° C., in the presence of increasing concentration of inhibitor. At the end of the reaction, RNA is precipitated with 10% TCA, and acid-insoluble RNA products are filtered on a size exclusion 96-well plate. After washing of the plate, scintillation liquid is added and radio labeled RNA products are detected according to standard procedures with a Trilux Topcount scintillation counter. The compound concentration at which the enzyme-catalyzed rate is reduced by 50% (IC₅₀) is calculated by fitting the data to a non-linear regression (sigmoidal).

Example C Determination of Compound Half-life in Human Hepatocytes

Test compounds are dissolved in dimethylsulfoxide (DMSO) to form a 10-mM stock solution. Primary human hepatocytes are cultured in 6-well plates and maintained in Williams E. medium containing Life Tech's proprietary supplement cocktail. The cell concentration is approximately 1.5-2 million cells per well. The plated human hepatocytes in 3 mL of medium per well are acclimated overnight (>18 h) in a cell culture incubator at 37° C., 5% CO₂. An aliquot (15 μL) of test compound stock solution is added into each well to achieve a final concentration of 50 μM. After 24 hours of incubation at 37° C., 5% CO₂, the incubation medium containing the test compound is aspirated off and replaced with 3 mL of blank incubation medium. The cells are then placed back into the incubator after collection of the O-hour time point. The time points for the NTP stability assay are: 0, 3, 6, 10, 24, and 48 h. The cell number (1.5 or 2 million cells per well) is used to normalize the test compound concentration from micromolar to pmol/million cells.

At each designated timepoint, the plate is taken out of the incubator and the incubation medium is removed from the designated well. The cells are washed twice with 700 μL of cold 0.9% NaCl in water, and the washing buffer is aspirated off following wash. The cells are then lysed by adding 700 μL of methanol/water (70/30) into the well. The cells are harvested using a cell lifter to remove them from the plate. The cell lysate is transferred into an Eppendorf tube and stored at −20° C. for at least 3 h. After vortexing the Eppendorf tube for 1 minute and centrifuging at 14,000 rpm for 10 minutes, the supernatant is transferred into a clean Eppendorf tube and dried down in a Speed-Vac. The residue is reconstituted with 500 μL of 1 mM ammonium phosphate, vortexed for 1 minute, and centrifuged at 14,000 rpm for 10 mins. An internal standard (N6-benzoyl adenosine) is added to a 50 μL aliquot of the supernatant and transferred into an auto sampler vial and subjected to LC-MS/MS analysis. For NTP quantitation, NTP stock solutions at 3 mM in water are diluted with water to achieve a set of calibration spiking solutions. An aliquot of the spiking solutions is spiked into control cellular sample (from human hepatocytes incubated without test article and treated in the same manner as study samples) and the internal standard is added to form the NTP cellular calibration standards. The processed study samples and calibration standards are analyzed by LC-MS/MS to determine the NTP concentrations. Quantification of NTP from primary human hepatocytes is conducted using Analyst® software on a AB-Sciex® API 3200 tandem triple quadrupole mass spectrometer coupled to a Shimadzu® LC-20AD HPLC system with a Leap Technologies HTC PAL autosampler. The HPLC column is a Phenomenex Gemini C18 (3-μm particle size, 50×2 mm) column. Mobile Phase A consisted of 3 mM ammonium formate and 10 mM dimethyl hexylamine (DMHA) in water. Mobile Phase B consisted of 3 mM ammonium formate and 10 mM DMHA in 1:1 water/acetonitrile. The run time for each sample is 10 or 20 mins using a gradient LC separation coupled with negative ion MS/MS detection of NTP.

Example D Combination of Compounds

Combination Testing

Two or more test compounds are tested in combination with each other using an HCV genotype 1b HCV replicon harbored in Huh7 cells with a stable luciferase (LUC) reporter. Cells are cultured under standard conditions in Dulbecco's modified Eagle's medium (DMEM; Mediatech Inc, Herndon, Va.) containing 10% heat-inactivated fetal bovine serum (FBS; Mediatech Inc, Herndon, Va.) 2 mM L-glutamine, and nonessential amino acids (JRH Biosciences). HCV replicon cells are plated in a 96-well plate at a density of 10⁴ cells per well in DMEM with 10% FBS. On the following day, the culture medium is replaced with DMEM containing either no compound as a control, the test compounds serially diluted in the presence of 2% FBS and 0.5% DMSO, or a combination of compound 18 with one or more test compounds serially diluted in the presence of 2% FBS and 0.5% DMSO. The cells are incubated with no compound as a control, with the test compounds, or the combination of compounds for 72 h. The direct effects of the combination of the test compounds are examined using a luciferase (LUC) based reporter as determined by the Bright-Glo Luciferase Assay (Promega, Madison, Wis.). Dose-response curves are determined for individual compounds and fixed ratio combinations of two or more test compounds.

The method utilized for evaluating combination effects uses a program called MacSynergy II. MacSynergy II software is kindly provided by Dr. M. Prichard (University of Michigan). The Prichard Model allows for a three-dimensional examination of drug interactions and a calculation of the synergy volume (units: μM²%) generated from running the replicon assay using a checkerboard combination of two or more inhibitors. The volumes of synergy (positive volumes) or antagonism (negative volumes) represent the relative quantity of synergism or antagonism per change in the concentrations of the two drugs. Synergy and antagonism volumes are defined based on the Bliss independence model. In this model, synergy volumes of less than −25 indicate antagonistic interactions, volumes in the −25-25 range indicate additive behavior, volumes in the 25-100 range indicate synergistic behavior and volumes >100 indicate strong synergistic behavior. Determination of in vitro additive, synergistic and strongly synergistic behavior for combinations of compounds can be of utility in predicting therapeutic benefits for administering the combinations of compounds in vivo to infected patients.
